LAND-ROLLER BEARING.

Application filed April 30,

My invention relates to land roller construction and is directed toimprovement of the bearing boxes supporting the ends of the rollershafts.

In rollers of the typeknown as land packers or sub-soil packers inwhichone or more gangs of packer wheels or disks are assembled andclamped together on a shaft, it is sometimes desirable to'remove two orthree of the disks from the shaft and move the remaining disks in thegang apart from the middle so that a row of growing plants may bestraddled by the implement, and the principal object of my invention isto provide bearing boxes for the disk shafts that will be readilydetachable and removable, thereby permitting the roller shaft to bewithdrawn axially and one or more disks removed. A further object is toprovide adjustable clamping means in connectionwith the bearing boxesfor clamping the disks together on the shaft.

With these main objects in view, the invention resides in theconstruction and arrangement of parts or the equivalents thereofhereinafter described and claimed.

Referring to the drawings Fig. 1 is a plan view of one end of a landpacker embodying my invention;

Fig. 2 is a similar end view;

Fig. 3 is a vertical sectional view on an enlarged scale through one ofthe bearing boxes;

Fig. 4 is a plan view of one of the journal sleeves;

Fig. 5 is a detail view of a supporting bracket and sleeve viewed fromthe inner side; and

Fig. 6 is a detail view of a clamping collar.

In the present instance, I have illustrated my invention as applied to aland packer comprising a horizontal U-shaped main frame member 10, tothe front of which is pivoted a tongue 11, and the upper frame members12, 13 all rigidly connected together. The horizontal frame member 10 ispreferably formed of angle iron having one flange or web positionedhorizontally as shown in Figs. 1 and 2 and to this flange there isriveted or otherwise fixed on each side of the machine bearing brackets14, 15', in which are journaled front and rear shafts 16 carr ing gangsof packer wheels or disks 17. T e particular mannerin which the shafts16 are journaled in the brackets 14;

j cot-matter of my present invention and this construction will now bedescribed.

Each bracket 14 and 15 is formed with an opening 18 having oppositelateral ex tensions 18* and in this opening there is fitted a journalsleeve 19 which is provided with radial lugs or ears 20 engaging theextensions 18 referred to. The journal sleeve 19 is designed to extendoutwardly through the bracket about half its length and the lugs 20areformed with flanged portions 20 which engage the outer face of thebracket. The lugs 20 extend inwardly behind the bracket, as best seen inFig. 4, and are there provided with perforations receiving pins or bolts21 which engage the rear face of the bracket and constitute retainingelements preventing withdrawal of the journal sleeve. Within the journalsleeve 19 there is the usual wood bushing 22 which is held in positionby the inward projections 19' on sleeve 19 and the shaft 16 journaled inthe bushing is retained by the crown nut 23 threaded and locked on itsend in the usual manner. The outer end of the journal sleeve 19 isclosed by the hub cap 24 which is bolted or otherwise secured to cars 25on the sleeve. With the construction so far described, it will beevident that any one of the journal sleeves may be removed outwardlythrough the bearing bracket by simply removing the two retainingelements 21 on, the inner side of the supporting bracket and that whenthe journal. sleeves on. each end of a shaft 16 are thus removed, theshaft may be withdrawn axially from the disks 17 and the desired numberof disks removed and the shaft and journal sleeves then replaced, whenreplacing of the pins or bolts 21 will effectively secure the parts inassembled position. As means for clamping the disks together as well asfor forming a dust cap on the inner end of the journal sleeve, I providethe flanged clamping ring 26 which fits over the inner end of thejournal sleeve 19 in the manner best seen in Fig. 3 and has its outerface in contact with the side of the outer disk 17. In order that thedisks may be kept in contact with each other and any wear taken up whennecessary, each clamping ring 26 is formed on its upper side with aslotted extension 26 which preferably has its upper surface corrugatedto cooperate with a corrin combination. of parts, constitutes thesubgated cap 27 and the sleeve 19 is provided at its inner end with ascrew threaded opening which receives the end of a screw bolt 28 -passedthrough the cap 27 and the slot in I sleeve is tolloev withdrawn,as'abovedescribed, :it will also benecessary to remove the screw bolt 28as well as the retainingelements 21. The construction describedexemplifies the preferred form of my invention and such modificationsmay be made as fall withinthe.

. scope of the following claims I claim as my invention:

-1. Ina land roller, the'combination with thefra'me, shaft, and rollerthereon, of an roller, and axially adjustable connecting.

means between. the sleeve and clamping member. v

2; In a land roller, the combination with the frame, shaft, and rollerthereon, of an end bracket secured to the frame and formed with anopening, a journal sleeve of uniform diameter fitted in said opening andreceiving the end of the roller shaft, detachable retaining elementsattachedv to said sleeve and engaging the inner side of said bracket,and

the roller and secured to the inner end'of said sleeve by meanspermitting adjustment of said ring axially. V

In testimony whereof I aflix my signature.
